Playing with sound

Labsession today was fun! We played with sound… Well we played with a thing called Pure Data. A pretty basic piece of software that can detect input and through a visual interface you are able to alter the input into output you want. It has pretty advanced logic and you can have different kind of outputs, like playing sound, what’s even more fun is the fact that the thing can detect yourArduino board if it’s hooked up through a USB cable.

Now we did basic stuff we took a LDR (Light Dependent Resistor) and read out the current, the current was a factor to make the pitch of a sound signal. Even more fun it was when we hooked up a second LDR, that one we used to control the control the volume of the setup. Soon we were making music by waving our hands over the breadboard.
